Field surveys conducted during 2021 and 2022 in Western Sicily, Italy, revealed the presence of common fig trees severely affected by trunk crown root canker bark cracking. Moreover, conjunction with symptomatic tissues, same surveyed plants showed beetle holes internal wood galleries. The predominant Criphalus dilutus was previously reported attacking figs Sicily. Phylogenetic analyses based on multilocus DNA data different fungal taxa associated disease symptoms, including Botryosphaeria dothidea, Ceratocystis ficicola, Diaporthe foeniculina, Neocosmospora bostrycoides, N. perseae, Neofusicoccum luteum. Pathogenicity tests potted that all species were pathogenic to fig, C. ficicola spp. as most aggressive species. isolations from bodies emerging adult insects recovered samples confirmed spp., suggesting potential involvement their dissemination.

Pest categorisation of non‐EU Scolytinae on non‐coniferous hosts

Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding phloem (‘bark beetles’ subgroup) fungi inoculated into sapwood (‘ambrosia subgroup). Smaller subgroups feed and reproduce in seeds fruits, herbaceous plants. Some are polygynous, males initiate gallery chamber new host attract females. Others monogamous, females galleries. Many respond to primary volatile attractants emitted by some produce aggregation pheromones that conspecifics both sexes. attacking living hosts often associated with contribute weakening defences provide nutrients insects. inbreeding; offspring mate their sisters rarely leave natal tree. larvae all develop pupate within hosts. Based catalogues other published data, database was constructed providing information reproductive habits, geographic distribution Köppen–Geiger climate types countries where occur. were screened exclude following categories: (i) 708 conifers; (ii) 127 present at least four Member States (iii) 440 occurring areas climatic conditions not EU.

Se determinó la composición específica de escolitínos (Coleoptera: Curculionidae: Scolytinae) en tres huertas comerciales higo (Ficus carica L., Moraceae) Ayala, Morelos, México. En cada huerta se recolectaron muestras madera (directamente del árbol y suelo) forma bimestral (92 kg total) esperó a emergencia adultos. colectaron 22,075 especímenes clasificados dos tribus (Scolytini e Hylesini), cuatro géneros ocho especies. Los más diversos fueron Hypothenemus Xyleborus, con 3 Phloeotribus opimus Wood fue especie mayor prevalencia, dominancia número ejemplares por kilogramo colectada. Por vez primera registra al como hospedera H. crudiae (Panzer), rotundicollis (Eichhoff), Pycnarthrum hispidum Ferrari, X. ferrugineus affinis F. volvulus Infestaciones continuas aceleran el envejecimiento las plantaciones incrementan posibilidad transmisión patógenos.
